Carbon nanotubes and carbon onions for modification of styrene–acrylate copolymer nanocomposites

21-Mar-2015 | Remo Merijs‐Meri, Janis Zicans, Tatjana Ivanova, Juris Bitenieks, Alesya Paddubskaya, Polina Kuzhir, Sergey Maksimen ..., Polymer Composites, 2015

Styrene acrylate polymer (SAC) nanocomposites with various carbon nanofillers (multi‐walled carbon nanotubes, MWCNT, and onion like carbons, OLCs, annealed at two different temperatures) are manufactured by means of latex based and combined routes. Concentration of the carbon nanofillers is ...

Coassembly of Nanorods and Nanospheres in Suspensions and in Stratified Films

17-Mar-2015 | Héloïse Thérien‐Aubin, Ariella Lukach, Natalie Pitch, Eugenia Kumacheva, Angewandte Chemie International Edition, 2015

Abstract The entropically driven coassembly of nanorods (cellulose nanocrystals, CNCs) and nanospheres (dye‐labeled spherical latex nanoparticles, NPs) was studied in aqueous suspensions and in solid films. In mixed CNC‐latex suspensions, phase separation into an isotropic latex‐NP‐rich and a ...

Molecules, Vol. 20, Pages 4473-4482: Inhibitory Effect of Duabanga grandiflora on MRSA Biofilm Formation via Prevention of Cell-Surface Attachment and PBP2a Production

10-Mar-2015 | Santiago, Carolina ; Lim, Kuan-Hon ; Loh, Hwei-San ; Ting, Kang Nee, Molecules, 2015

Formation of biofilms is a major factor for nosocomial infections associated with methicillin-resistance Staphylococcus aureus (MRSA). This study was carried out to determine the ability of a fraction, F-10, derived from the plant Duabanga grandiflora to inhibit MRSA biofilm formation. Inhibition ...

In situ studies of bovine serum albumin adsorption onto functionalized polystyrene latices monitored with a quartz crystal microbalance technique

03-Mar-2015 | Manel Beragoui, Chadlia Aguir, Mohamed Khalfaoui, Eduardo Enciso, Maria José Torralvo, Laurent Duclaux, Laurence Rei ..., Journal of Applied Polymer Science, 2015

ABSTRACT The adsorbability of bovine serum albumin (BSA) onto poly(styrene‐co‐itaconic acid) (PS–IA), poly(styrene‐co‐hydroxyethyl methacrylate) (PS–HEMA), poly(styrene‐co‐acrylic acid) (PS–AA), and poly(styrene‐co‐methacrylic acid) (PS–MAA) latices were investigated with a quartz crystal ...

Shear-Dependent Interactions in Hydrophobically Modified Ethylene Oxide Urethane (HEUR) Based Coatings: Mesoscale Structure and Viscosity

03-Mar-2015 | Antony K. Van Dyk; Tirtha Chatterjee; Valeriy V. Ginzburg; Alan I. Nakatani, Macromolecules, 2015

We have investigated the in situ mesoscale structure of paint formulations under shear using ultra small-angle neutron scattering (rheo-USANS). Contrast match conditions were utilized to independently probe the latex binder particle aggregates and the TiO2 pigment particle aggregates. Two ...

Suppressing the long‐chain branching in the synthesis of poly(styrene‐b‐butyl acrylate‐b‐styrene) in RAFT emulsion polymerization by tuning the interfacial properties

27-Feb-2015 | Yunlong Guo, Xiang Gao, Yingwu Luo, Journal of Polymer Science Part A: Polymer Chemistry, 2015

ABSTRACT Reversible addition‐fragmentation chain transfer (RAFT) emulsion polymerization is becoming an important technique to synthesize the latex of block copolymers. A previous study showed that in the synthesis of polystyrene‐b‐poly(butyl acrylate)‐b‐polystyrene triblock copolymer via RAFT ...

Influences of feeding strategies on AA and MAA carboxylated latexes

24-Feb-2015 | Martin Ocepek, Peter Berce, Tina Razboršek, Jožefa Zabret, Lei Meng, Mark D. Soucek, Journal of Applied Polymer Science, 2015

ABSTRACT Semibatch, power feed, and shot‐addition feeding strategies were employed to synthesize carboxylated latex under acidic conditions, using emulsion polymerization. As a source of carboxyl groups, acrylic (AA) or methacrylic acid (MAA) was used. The distribution of carboxyl groups ...

Nanopipet‐Based Resistive Pulse Sensing to Follow Alterations in the Size and Concentration of Nanoparticles During Membrane Filtration

20-Feb-2015 | Péter Terejánszky, István Makra, Alda Lukács, Róbert E. Gyurcsányi, Electroanalysis, 2015

Abstract We propose a calibration‐free resistive pulse sensing (RPS) methodology based on nanopipets to follow the size and concentration changes of nanoparticles during size‐selective separation processes. The study was performed with monodisperse latex nanoparticles and their mixtures that ...

Synthesis and Redispersibility of Poly(styrene-block-n-butyl acrylate) Core–Shell Latexes by Emulsion Polymerization with RAFT Agent–Surfactant Design

20-Feb-2015 | Feizhou Wang; Yingwu Luo; Bo-Geng Li; Shiping Zhu, Macromolecules, 2015

A coagulatable and redispersible poly(styrene-block-n-butyl acrylate) (PS-b-PnBA) copolymer latex system was developed. A series of PS-b-PnBA diblock copolymers with the PnBA content up to 70 wt % were prepared via a reversible addition–fragmentation chain transfer (RAFT) emulsion polymerization. ...

Optimization of synthesis and characterization of oxidized starch‐graft‐poly(styrene‐butyl acrylate) latex for paper coating

19-Feb-2015 | Shijie Cheng, Wenpeng Zhao, Yumin Wu, Starch - Stärke, 2015

Abstract Oxidized starch‐graft‐poly(styrene‐butyl acrylate)[OS‐g‐P(ST‐BA)] latex with core‐shell structure was synthesized by the graft copolymerization of OS with ST and n‐butyl acrylate (BA) via emulsion polymerization. A three‐level, four‐variable Box‐Behnken design was employed to ...
